REFRIGERATING UNIT Filed July 22, 1937 2 Sheets-Sheet 2 Patented Jan. 3, 1939 UNITED STATES PATENT OFFICE 3 Claims.

This invention relates to refrigerating devices, and particularly to means for cooling vehicles such as automobiles.

An object, of the invention is to provide a container for a refrigerant such as dry ice, so held that air circulating over it will be cooled and delivered to the interior of an automobile, means being provided for effecting a live circulation of air from the exterior to the interior of the vehicle.

While the invention is primarily for use with automobiles, the inventor does not wish to be limited to such use, and therefore in the further description of the invention, the term vehicle will be employed, and it is to be understood that this may include any traveling equipment, and comprehends of course trailers, now being used in comparatively large numbers in transportation and as habitations.

It is an object furthermore to provide an inexpensive container or holder for the refrigerant, and while the invention is more particularly adapted for use in connection with dry ice, the inventor does not wish to be limited with respect to the type of refrigerant employed.

Itis' furthermore an object of the invention to provide a container, holder or carrier for the refrigerant, which can be expeditiously applied to or removed from the vehicle, the said device being held in place by cooperating instrumentality, preferably forming a part of ordinary vehicles; and the said device is provided with means whereby it may be anchored securely in place during its use.

With the foregoing and other objects in view, the invention consists inproviding a refrigerant carrier, and in the details of construction and the arrangement and combination of parts to be hereinafter more fully described and claimed.

In these drawings Fig. 1 illustrates a perspective view of the refrigerating device, with the parts in dotted lines denoting parts of the vehicle in association with which it is employed.

Fig. 2 is a plan view of a blank or sheet shaped for folding to produce the holder.

Fig. 3 is a sectional view on the lines 33 of Fig. 5.

Fig. 4 is a sectional view on the line 4-4 of Fig. 5, and

Fig. 5 is a view in elevation of the front end of the holder.

In these drawings, the holder is shown as rectangular, and that is the preferable-shape, although it is optional as to the dimensions it may have.

In the present embodiment of the invention, the holder or container, which, for the purpose of this description, will be termed holder, is formed in one piece, and preferably the material is paste board corrugated stock or other appro- 5 priate material. The blank from which the holder is made, shown in Fig. 2, and which comprises a body portion Ill of suitable dimensions, is preferably scored on the lines ll, l2, l3 and lb, or at least it is preferably folded onthese lines, and 10 the scoring provided to facilitate the manipulation.

, It is shown that the member ID has wings or extensions l4 and I5, which when folded on the lines l6 and I1 respectively, form the front and 16 rear ends of the holder. The part M has an angularly disposed cut-out portion or recess l8, which when the blank is folded forms an aperture in the front end of the holder through which air enters said holder. When the blank is 20 folded, the part or section l9 thereof forms the bottom of the holder, and the section 20 forms a cover or flap overlying the ends of the holder. The sections I4 and I5 have under-cutrecesses forming beveled edges 2| and 22, which are par- 25 allel to each other when the ends are positioned at right angles to the bottom I9; and the edges 23 and 24 of the respective portions 14 and I5 support the cover 20 when it overlies the ends of the holder.

As shown in Figs. 1 and 5, the portion 25 of the blank is positioned vertically or at right angles to the bottom, and it is integral with said bottom. The extremity of the blank is bent on the line Mb to form the angle 21 between the portion 25, which latter forms the inner side of the holder, and the flange 26. The flange extends downwardly in engagement with the beveled edges 2| and 22 at the ends of the holder, thus creating an opening between the top and the inner edge of the flange, which opening flares inwardly for the purpose of permitting the air current to expand as it enters the vehicle.

The inclined flange has a further function in that a seat is formed externally at the angle 21, in which the edge of the glass A or a frame of thc glass of a window of the vehicle may be seated to retain the holder in engagement with the window frame B, so that the holder will be anchored in place, and the said flange will act somewhat as a hanger for supporting the container.

The wings or extensions l4 and I5 are further scored as at Ma. and I511. respectively, and when the blank is folded, the wings are likewise folded on the lines just mentioned. The portions [9a. of the blank, between the lines H and [2, form the outer wall of the container, it being understood that the blank is folded on the line [2, which is at the junction of the said outer wall and the bottom, which bottom is formed by the section IQ of the blank. When the wings are folded on the lines Ma and l5a, and they are assembled with relation to the bottom IS, the bent portions of the wings will overlie a portion of the bottom, as shown at C and D, and reinforce the bottom.

A suitable retaining means, such as E, may be provided at the joints of the container when folded, such retaining means being in the nature of paper or other reinforced device adhesively secured at the proper location.

I claim:

1. In a refrigerating unit, a refrigerant holder consisting of a container for refrigerant, having means by which it is suspended in a window opening of a vehicle, said holder having a front end with an opening therein, and a side opening discharging in the vehicle, through which air circulates from the exterior of the vehicle over the refrigerant, and enters the said vehicle; the said holder comprising a cover, a bottom, an outer side wall, an inner side wall, and ends formed integrally, and the said inner wall having a depending flange at its top below the cover, and forming with the cover a chute through which air enters the vehicle.

2. In a refrigerating unit, a refrigerant holder consisting of a container for refrigerant, having means by which it is suspended in a window opening of a vehicle, said holder having a front end with an opening therein, and a side opening discharging in the vehicle,-thr0ugh which air circulates from the exterior of the vehicle over the refrigerant, and enters the said vehicle; the said holder comprising a cover, a bottom, an outer side wall, an inner side wall, and ends formed integrally, the ends of the container having notches in their edges, one wall of each of which is beveled, the side inner wall having an extension at an angle thereto, the said inner wall at its angular portion fitting in the recesses of the ends and the extension thereof forming a depending flange engaging the beveled edges of the ends, and forming a seat for the reception of a sliding window of a vehicle when said window is raised, thereby holding the receptacle in place in the open portion of the window.

3. In a refrigerating unit, a refrigerant holder consisting of a container for refrigerant, having means by which it is suspended in a window opening of a vehicle, said holder having a front end with an opening therein, and a side opening discharging in the vehicle, through which air circulates from the exterior of the vehicle over the refrigerant, and enters the said vehicle; the said holder comprising a cover, a bottom, an outer side wall, an inner side wall, and ends formed integrally, said ends having a foldable portion overlying the bottom when the blank is folded to form said holder, and the said ends having recessed edges forming seats, and the said inner wall having an integral depending flange, and the said inner wall at the junction of the flange being seated in the recesses of the ends with the flange engaging the beveled edges of the recesses, whereby a seat is formed at the said angle-for the engagement of a window of a vehicle when said window is adjusted to partially open the window, and the said angularly disposed parts forming a hanger by which the holder is suspended.
